Now to make sure I do the rescission process right the first time through. Any tips?
No trick to it. There are any number of sample rescission letters here, just use the search window near the top, right of this page.
Make sure that all signers of the contract sign the letter.
The address is in Las Vegas, not where you signed the contract.
Send it USPS Certified w/return receipt.
Do it TODAY. The post office is closed tomorrow, even though it counts in the day totals.
